Multiple Pancreatoduodenal Artery Arcade Aneurysms Associated with Celiac Axis Root Segmental Stenosis Presenting as Aneurysm Rupture.

Abstract
A 57-year-old woman was admitted to our unit suffering from hemorrhagic shock and upper abdominal pain. An enhanced computerized tomography (CT) scan evidenced a large retroperitoneal hematoma due to visceral arteries aneurysm rupture and a significant celiac axis root segmental stenosis due to median arcuate ligament compression. A selective splanchnic arteries angiography showed 3 saccular pancreaticoduodenal artery arcade aneurysm (PDAAs), 2 in the inferior posterior pancreaticoduodenal artery, and 1 smaller in the superior anterior pancreaticoduodenal artery. The largest aneurysm showed evident rupture signs. Both inferior PDAAs were successfully treated via endovascular coil embolization. The celiac trunk stenosis and small inferior PDAA did not require treatment. A CT scan control at 1-year follow-up did not reveal any new PDAAs. In cases of celiac artery trunk (CAT) steno-occlusive lesions, multiple aneurysms can develop in the pancreaticoduodenal arcade. PDAAs should be treated because of high rupture risk, regardless of diameter. Although endovascular treatment via coil embolization represents the treatment of choice nowadays, a simultaneous treatment of the associated CAT lesions is still debated. However, in cases of aneurysm embolization alone, one cannot exclude that other PDAAs might develop in these patients in the future. Close monitoring and accurate long-term follow-up is highly recommended in these cases.
